Detailed Description

The SoBlinker class is a cycling switch node.

This switch node cycles its children SoBlinker::speed number of times per second. If the node has only one child, it will be cycled on and off. Cycling can be turned off using the SoBlinker::on field, and the node then behaves like a normal SoSwitch node.

FILE FORMAT/DEFAULTS:

Blinker {
on TRUE
}

Member Function Documentation

◆ getTypeId()

SoType SoBlinker::getTypeId ( void  ) const
virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Usage example:

void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the predefined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the top level superclasses for the various class groups.

Reimplemented from SoSwitch.

◆ getFieldData()

const SoFieldData * SoBlinker::getFieldData ( void  ) const
protectedvirtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoSwitch.

◆ getBoundingBox()

void SoBlinker::getBoundingBox ( SoGetBoundingBoxAction action)
virtual

Action method for the SoGetBoundingBoxAction.

Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.

Nodes influencing how geometry nodes calculate their bounding box also override this method to change the relevant state variables.

Reimplemented from SoSwitch.

◆ write()

void SoBlinker::write ( SoWriteAction action)
virtual

Action method for SoWriteAction.

Writes out a node object, and any connected nodes, engines etc, if necessary.

Reimplemented from SoSwitch.

◆ notify()

void SoBlinker::notify ( SoNotList l)
protectedvirtual

Notifies all auditors for this instance when changes are made.

Reimplemented from SoSwitch.

Member Data Documentation

◆ speed

SoSFFloat SoBlinker::speed

◆ on

SoSFBool SoBlinker::on

Controls whether cycling is on or off.
